Im not sure but i think it is 15 - x
Answer:
11.25
Plan B as it is cheaper
Yes as in both equations the change in y repeats
(25,12.5)
(E I dont know how to do)
Step-by-step explanation:
22.50 divided by the slope

They cross each other on the graph at 25 texts and 12.50 dollars
Setting y=0, we can solve the quadratic equation or factor the polynomial to
(5x-1)•(5x-1) = 0
(5x-1)^2 = 0
5x-1=0
x=1/5 or 0.2
So there is only one root and the function intersects the x-axis at only one point.
The answer is B. 1.
